bcachefs: Fix btree_trans list ordering
The debug code relies on btree_trans_list being ordered so that it can
resume on subsequent calls or lock restarts.
However, it was using trans->locknig_wait.task.pid, which is incorrect
since btree_trans objects are cached and reused - typically by different
tasks.
Fix this by switching to pointer order, and also sort them lazily when
required - speeding up the btree_trans_get() fastpath.
